Ice in East Antarctica a Bigger Threat Long Term

TROLL RESEARCH STATION, Antarctica —  Antarctica's western ice sheet is pushing ever faster into the sea, but scientists know an even greater long-term threat lies here in the vast, little-explored whiteness of east Antarctica. An "absolutely titanic" store of ice that sits atop the east Antarctic plateau should be more closely monitored by glaciologists, the world's thinly spread corps of ice specialists, says Ted Scambos, a leading U.S. expert whose team last weekend finished a two-month scientific expedition across the forbidding plateau.
